"""Import one or more playlist for the given sound. Attach it to the provided
sound.

Playlists are in CSV format, where columns are separated with a
'{settings.IMPORT_PLAYLIST_CSV_DELIMITER}'. Text quote is
{settings.IMPORT_PLAYLIST_CSV_TEXT_QUOTE}.
The order of the elements is: {settings.IMPORT_PLAYLIST_CSV_COLS}

If 'minutes' or 'seconds' are given, position will be expressed as timed
position, instead of position in playlist.
